Description

Die Erfindung betrifft einen Transportbetonmischen mit einer Getriebeanordnung mit einem die Antriebswelle der Betonmischtrommel über einen ein Planetengetriebe antreibenden Hydromotor.The invention relates to ready-mixed concrete mixing with a gear arrangement with a Drive shaft of the concrete mixing drum over a a hydraulic motor driving a planetary gear.

Aus der französischen Patentschrift FR 2 181 171 ist ein Mischergetriebe bekannt, bei weichem antriebsseitig über einen schnellaufenden Hydromotor (ca. 70 ccm) über die erste Stufe eines Planetengetriebes in die zweite Stufe des Planetengetriebes eingetrieben wird. Das Hohlrad der zweiten Stufe Planetengetriebe und das Mischergetriebegehäuse bilden dabei ein Teil. Der Planetenträger der zweiten Stufe bildet gleichzeitig die Verbindung zu einem Abtriebsflansch. Insgesamt hat dieses bekannte Mischergetriebe eine Übersetzung von l = ca. 100. Damit ergibt sich auf der Abtriebsseite ein erforderliches Hydromotormoment von 7000 ccm/U x Druckdifferenz Abgesehen davon daß diese bekannte Anordnung technisch recht aufwendig ist, besteht ein erheblicher Nachteil hinsichtlich der Geräuschemission während des Betriebes.From French patent FR 2 181 171 a mixer gear is known, in soft on the drive side via a high-speed hydraulic motor (approx. 70 cc) over the first stage of a Planetary gear in the second stage of the planetary gear is driven. The ring gear of the second Stage planetary gear and the mixer gear housing form part of it. The planet carrier the second stage forms the connection at the same time to an output flange. Overall, this one known mixer gearbox a translation of l = approx. 100. This results on the output side a required hydraulic motor torque of 7000 ccm / rev x pressure difference Apart from that that this known arrangement is technically quite complex there is a significant disadvantage in terms of the noise emission during operation.

In der eidesstattlichen Versicherung von Hern Schweizer, welcher bei der Faliebherr- Mischtechnik GmbH beschäftigt ist, von 13.1.2000 ist ein geräuschreduzierter Antrieb einer Mischtrommel, bestehend aus einem laugsamlaufenden und ein hohes Drehmoment abgebenden Radialkolbenmotor, einem einstufigen Planetengetriebe und einer Bogenzahnkupplung beschrieben, wobei über eine Kupplungsmuffe und einen Zwischenflansch der Radialkolbenmotor montiert ist. Gemäß der eidesstattlichen Versicherung wurde des Antrieb auf der "bauma 89" in München von 10.-16.4. 1989 ausgestellt.In the affidavit by Hern Schweizer, which is employed by Faliebherr-Mischtechnik GmbH, from 13.1.2000, a noise-reduced drive of a mixing drum, consisting of a slow-running and high-torque radial piston motor, a single-stage planetary gear and an arc clutch is described, whereby over a coupling sleeve and an intermediate flange of the radial piston motor is mounted. According to the affidavit, the drive was switched on the "bauma 89" in Munich from 10.-16.4. Issued in 1989.

Demzufolge besteht die Aufgabe der Erfindung darin, einen Transportbetonmischer mit einer Getriebeanordnung zu Schaffen bei welchem eine wesentliche Geräuschreduzierung im Betrieb und ein kompakter Aufbau der Getriebeanordnung realisiert sind.Accordingly, there is an object of the invention in creating a ready-mixed concrete mixer with a gear arrangement in which a substantial reduction in noise during operation and a compact structure of the gear arrangement are realized.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst. Zweckmäßige Weiterbildungen sind in den Unteransprüchen festgelegtThis object is achieved by solved the features of claim 1. expedient Further training is in the subclaims set

Danach ist der Hydromotor ein im Mischergetriebegehäuse abtriebsseitig nicht gelagerter, langsam laufender und ein hohes Drehmoment abgebender Radialkolbenmotor, dessen interne Kräfte mittels einer Zentrierbuchse über ein Lager in einen Zwischenflansch einleitbar sind, so daß das Getriebe ein einstufiges Planetengetriebe ist und daß die Getriebewelle direkt mit einem Sonnenrad gekoppelt ist, dessen Abtrieb über einen Planetenträger auf eine Bogenzahnkupplung erfolgt, welches das Drehmoment an die Antriebswelle der Mischertrommel überträgt.Then the hydraulic motor is in the mixer gearbox not slowly supported on the output side running and delivering a high torque Radial piston motor, whose internal forces by means of a centering bush Can be introduced into an intermediate flange via a bearing are, so that the transmission is a single-stage planetary gear is and that the gear shaft directly with a sun gear is coupled, the output via a planet carrier on a curved tooth coupling takes place, which the torque to the Transmits the drive shaft of the mixer drum.

Mit dem Erfindungskonzept ist es nunmehr möglich, auf die Erststufe des bekannten Mischergetriebes vollständig zu verzichten, mit einer Obersetzung von ca. 7:1 in der einzigen vorgesehenen Getriebestufe und ebenso 7000 ccm x Druckdifferenz - Abtriebsmoment zu erzielen. Inbesondere ist es möglich, da nur die internen Kräfte des Hydromotors beispielsweise durch Axiallager in den Zwischenflansch eingeleitet werden, um ein sehr kompaktes Getriebe zu schaffen.It is now with the concept of the invention possible to the first stage of the well-known mixer gear to do without completely, with a translation of approximately 7: 1 in the only provided Gear stage and also 7000 ccm x pressure difference - Achieve output torque. In particular is it is possible because only the internal forces of the hydraulic motor for example by thrust bearings in the intermediate flange to be introduced to a very compact Creating gears.

Das erfindungsgemäße Mischergetriebe besteht aus dem einstufigen Planetengetriebe, dessen Antrieb durch ein Sonnenrad erfolgt. Der Antrieb erfolgt über den Planetenträger und eine Bogenzahnkupplung, welcher einen Flansch sowie die Lagerung der Mischertrommel beinhaltet. Demzufolge ist es möglich, den Radialkolbenmotor auf der Abtriebsseite überhaupt nicht zu lagem, wobei lediglich seine internen Kräfte abgestützt werden. Die Getriebewelle ist direkt mit dem Sonnenrad des Planetengetriebes gekoppelt, wobei die Getriebewelle auch mit der Sonnenradverzahnung einstü kig ausgebildet sein kann.The mixer gear according to the invention exists from the single-stage planetary gear, whose Driven by a sun gear. The drive takes place via the planet carrier and an arc tooth coupling, which a flange as well as the Storage of the mixer drum included. As a result, it is possible to use the radial piston motor on the Output side not lagem at all, but only its internal powers are supported. The gear shaft is directly with the sun gear of the planetary gear coupled, the gear shaft also with the sun gear teeth kig can be formed.

Weitere Vorteile ergeben sich aus der nachfolgenden Erläuterung der Erfindung an einem Ausführüngsbeispiel anhand der beigefügten Zeichnung, in welcher eine Schnittansicht der Getriebeanordnung mit angeschlossenem Radialkolbenmotor und der Antrieb für die Mischertrommel gezeigt sind.Further advantages result from the following Explanation of the invention using an exemplary embodiment based on the attached drawing, in which a sectional view of the gear arrangement with connected radial piston motor and the drive for the mixer drum shown are.

Wie in der Zeichnung gezeigt ist, ist ein Radialkolbenmotor 100 mit Hilfe von Gewindestiften an einen Zwischenflansch angeschlossen. Dabei ist eine Sonnenradwelle mittels einer Zentrierbuchse 24 und einem Kegelradlager 23 auf der Abtriebsseite des Radlalkolbenmotors drehbar gelagert. Dieser Zwischenflansch 18 ist seinerseits fest mit dem Mischergetriebegehäuse 1 verbunden. Radiale Kräfte, die auf das im Radialkolbenmotor 100 befindliche Wellenende einwirken konnten, treten bei dieser Ausbildung nicht auf.As shown in the drawing is a radial piston motor 100 using grub screws connected to an intermediate flange. It is a sun gear shaft by means of a centering bush 24 and a bevel gear bearing 23 on the output side of the radial piston engine rotatably mounted. This intermediate flange 18 is in turn fixed the mixer gear housing 1 connected. radial Forces acting on the radial piston motor 100 Shaft end could act, join of this training.

An der Sonnenradwelle 2 befinden sich ein O-Ring, an der linken Seite der Zentrierbuchse 24 befindet sich eine Ölabdichtung; auch der Zwischenflansch 18 ist über eine Wellendichtung 5 mit der Zentrierbuchse 24 verbunden.There is an O-ring on the sun gear shaft 2, on the left side of the centering bush 24 there is an oil seal; also the intermediate flange 18 is with a shaft seal 5 the centering bush 24 connected.

In dem gezeigten Ansführungsbeispiel weist die Sonnenradwelle 2 ein mit ihr einstöckig ausgebildetes Sonnenrad auf, welches mit Planetenrädern 13 kämmt, wobei jedes Planetenrad 13 kraftschlüssig mit einem Planetenträger 12 verbunden ist. Dieser Planetenträger steht mit seinem freien Ende in Eingriff mit einer Bogenzahnkupplung, die im Ausführungsbeispiel ein Balligzahn-Stimrad 47 umfaßt Dieses auf einer Antriebswelle 3 sitzende Stirnrad 47 übertragt nunmehr das Drehmoment auf diese Welle 3. Um die im Betrieb des Mischers auftretenden Kräfte ausgleichen zu können, ist die in einen Abtriebsflansch 40 übergehende Welle 3 im Mischergetriebegehäuse 1 mittels eines Pendelrollenlagers gelagert. Dies ist als solches bekannt und braucht nicht näher erläutert zu werden.In the example shown, points the sun gear shaft 2 is one-piece with it Sun gear, which with planet gears 13 meshes, each planet gear 13 non-positively connected to a planet carrier 12 is. This planet carrier stands with its free End engaged with an arch tooth coupling, the in the exemplary embodiment, a spherical tooth impeller 47 includes this sitting on a drive shaft 3 Spur gear 47 now transmits the torque on this shaft 3. In order to operate the mixer To be able to compensate for occurring forces shaft 3 merging into an output flange 40 in the mixer gear housing 1 by means of a spherical roller bearing stored. This is known as such and need not be explained in more detail.

Erfindungswesentlich ist die Art der Kombination des beschriebenen Radialkolbenmotors mit dem Mischergetriebeteil. Für einen separaten Betrieb eines oder beider Teile dieser Kombination sind gegenüber zusätzliche wesentliche Bauteile erforderlich. The nature of the combination of the is essential to the invention described radial piston motor with the mixer gear part. For a separate operation of a or both parts of this combination are opposite additional essential components required.

Mit der beschriebenen Anordnung ist im Betrieb des Mischerfahrzeuges ein wesentlich im Verhältnis zum Stand der Technik reduzierter Geräuschpegel erreichbar, und zwar auf der Basis, daß ein Langsamläufer vorgesehen ist und seine Anbindung an das Getriebe direkt mit der Getriebewelle 2 über eine Nabenverzahnung folgt, Erfindungsgemäß wird ein Ausgleichsmechanismus einmal zwischen dem sehr genau zu führenden Rotationszylinder und andererseits der Getriebestufe hergestellt. Da diese Teile, insbesondere der Rotationszylinder einen sehr genauen Planlauf benötigt, wird im Bereich des Pianetengetriebes mit relativ Spiel gearbeitet; durch die besondere Lagerung werden aber aus dem Getriebe keine Relativbewegungen auf die Sonnenradwelle 2 aufgebracht, weil die Funktionsgruppen "Hydromotor" in ihrer Funktionssicherheit sonst nachteilig beeinflußt wird. Demzufolge werden die Innenkräfte des Hydromotors über ein separates Lager aufgenommen, wobei als Übermittler dieser Funktion auch die Zentrierbuchse 24 dient. Somit wird der Rotationszylinder zentriert und die Axialkraftanlage erfolgt auch an dieser Stelle. Das Lager 23 bewerkstelligt einmal die Innenkräfte des Radialkolbenmotors, das sind die in der Zeichnung nach rechts wirkenden, eindeutig bestimmbaren Innenkräfte und darüber hinaus auch die Zentrierung der Rotationsgruppe.With the arrangement described is in operation of the mixer vehicle an essential ratio reduced noise level to the state of the art achievable, based on that a slow runner is provided and his Connection to the gearbox directly with the gear shaft 2 follows via a toothing, according to the invention becomes a balancing mechanism once between the very precise rotating cylinder and on the other hand the gear stage manufactured. Because these parts, especially the rotary cylinder needs a very precise axial runout becomes relative in the area of the pianete gear Game worked; due to the special storage but no relative movements from the gear applied to the sun gear shaft 2 because the functional groups "hydraulic motor" in their functional reliability is otherwise adversely affected. As a result, the internal forces of the hydraulic motor recorded via a separate warehouse, whereby as a transmitter of this function also the centering bush 24 serves. Thus the rotary cylinder centered and the axial power system also takes place this place. The bearing 23 accomplished once the internal forces of the radial piston motor, that are those that appear to the right in the drawing are clear determinable internal forces and beyond also the centering of the rotating group.

Die Gruppe "Hydromotor" ist vom Ölkreislauf her gegenüber dem Getriebe abgedichtet (über den O-Ring 60 und auch über die Wellendichtung 5). Getriebeseitig wird das von dem Langsamläufer gelieferte Drehmoment im Verhältnis der Übersetzung auf die Abtriebsseite des Getriebes übertragen. Die Geräuschreduzierung im Betrieb des Betonmischers ergibt sich im Prinzip durch die besondere Auswahl des Hydromotors als Langsamläufer und durch die Tatsache, daß eine relativ schnell laufende Getriebestufe entfällt, die aufgrund der hohen Zahneingriffsfrequenz wesentlich zur Geräuschemission beiträgt. Die vorgesehene Getriebestufe läuft demzufolge erheblich langsamer, so daß die Geräuschemission praktisch entfällt. Hierzu tragen auch die oben erläuterten Bauteile bei, nämlich der Zwischenflansch 18, die Zentrierbuchse 24 und die Welle 2.The group "hydraulic motor" is from the oil circuit sealed against the gearbox (above the O-ring 60 and also over the shaft seal 5). On the transmission side, this is done by the slow runner delivered torque in the ratio of the translation transferred to the output side of the gearbox. The noise reduction in the operation of the concrete mixer results in principle from the special Selection of the hydraulic motor as a slow runner and by the fact that a relative fast running gear stage is eliminated due to the high tooth mesh frequency significantly Noise emission contributes. The intended gear stage therefore runs much slower, so that the noise emission is practically eliminated. The components explained above also contribute to this at, namely the intermediate flange 18, the centering bush 24 and the wave 2.

Durch den Zwischenflansch 18 findet eine Zentrierung der beiden Gehäuse (Mischergetriebegehäuse 1, Gehäuse des Radialkolbenmotors 100) statt.Centering takes place through the intermediate flange 18 of the two housings (mixer gear housing 1, housing of the radial piston motor 100) instead of.

Am-freien Ende der Sonnenradwelle 2 ist ein Axiallager 41 vorgesehen.At the free end of the sun gear shaft 2 is a Axial bearing 41 is provided.
